The attack happened an hour before he allegedly abducted Amy Lord from outside her South Boston apartment. Lord was later found dead, and Alemany has been charged in her murder.

The woman who survived her attack told News Center 5, "He just came out of nowhere, assaulted me. He hit me, choked me and later told me he had mistaken me for somebody."

The attacker told her that he was looking for another female with a baby and a male companion.

When the attack ended, he walked off. She said he was not afraid.

Alemany is charged in four violent attacks. He allegedly attacked a different woman in fall 2012 in Boston's Mission Hill neighborhood. The victim grabbed his wallet. At the time, police had leads to his identity that were not pursued.

"They should have gotten him then. It's because they didn't do their jobs there's three more victims out there and somebody is dead," the assault victim said.

She said she and the two surviving victims must speak for Lord. She said they want justice "mostly for her, for Amy, because she's the one that's not here to defend herself."
